What is the primary difference between a split heat pump and a packaged heat pump?

The primary distinction between a split heat pump and a packaged heat pump lies in the configuration of their components. A split heat pump consists of two separate units: an indoor unit placed inside the home, which contains the evaporator coil, and an outdoor unit that houses the compressor and condenser. This separation allows for greater flexibility in installation since the indoor unit can be strategically placed for optimal heat distribution and aesthetic considerations within the building.

In contrast, a packaged heat pump combines all components into a single unit that is typically installed outside or on the roof of a building. While this design can be advantageous for space savings and simplified installation, it does not offer the same installation flexibility as a split system.

The other options relate to efficiency, capacity, and installation costs, but these factors can vary based on specific models and circumstances rather than the inherent design differences between split and packaged systems. Therefore, recognizing the separate indoor and outdoor units as the hallmark of a split heat pump is crucial in understanding the fundamental differences between these two types of heat pumps.
